Sveltest Testing Documentation Testing patterns for Svelte 5 with vitest-browser-svelte Use locators, never containers page.getByRole('button', { name: 'Submit' }) container.querySelector('button') Always await element assertions await expect.element(locator).toBeVisible() expect(element).toBeVisible() Use semantic queries for accessibility page.getByRole('button'), page.getByLabelText('Email') page.getByTestId('submit-btn')


        import { describe, expect, test } from 'vitest';
        import { render } from 'vitest-browser-svelte';
        import { page } from '@vitest/browser/context';
        import Button from './Button.svelte';

        test('renders button with text', async () => {
          render(Button, { text: 'Click me' });
          await expect.element(page.getByRole('button', { name: 'Click me' })).toBeVisible();
        });


        test('handles click event', async () => {
          const { component } = render(Counter);
          await page.getByRole('button', { name: '+' }).click();
          await expect.element(page.getByText('Count: 1')).toBeVisible();
        });

Clicking submit buttons with SvelteKit enhance Test form state directly instead of clicking submit Elements with CSS animations may not be clickable Use { force: true } for clicking animated elements
